Abstract
The paper describes a reflective intelligent surface (RIS) assisted by computer vision (CV). A RIS can reflect the transmitter’s signal into shadow regions with low signal strength thus increasing the coverage area of a communication system. CV assists the RIS in searching for and tracking potential users. Information about user’s position is used to direct the RIS beam towards the user. Operation of CV algorithms and their integration in the RIS control loop is demonstrated. Increase in the received signal power of 15–20 dB in non-line of sight (NLOS) situations due to RIS operation is achieved. The system has a low cost and power consumption.
期刊介绍：
This journal establishes a dedicated channel for physicists, material scientists, chemists, engineers and computer scientists who are interested in photonics and nanostructures, and especially in research related to photonic crystals, photonic band gaps and metamaterials. The Journal sheds light on the latest developments in this growing field of science that will see the emergence of faster telecommunications and ultimately computers that use light instead of electrons to connect components.
